To all whom it may concern:

Be it known that I, CLARENCE W. WAD- DELL, citizen of the United States,residing at Dallas, in the county of Dallas and State of Texas, haveinvented certain new and useful Improvements in Interlocking Tiles, ofwhich the following is a specification.

This invention pertains to new and useful improvements in interlockingtiles.

In. the carrying out of the invention the primary object is to obviate acontinuous transverse mortar joint so that all liability of moisturepassing through the wall is eliminated and a more substantial wallbuilt.

The particular construction adopted provides a double lock in that eachtile has a mortise in its bottom for the reception of a tenon or rib onthe under-lying tile; while on its top it has a tenon or rib enteringthe superimposed tile.

The tile is formed with longitudinal air spaces which run parallel withthe courses of the wall, but most important is the provision of verticalair ducts formed by the registration of vertical air wells in the tilesso positioned that they will register when the tiles are set up.

Other objects will be apparent from a perusal of the followingspecification and the invention will be more readily understood byreference to the accompanying drawings in which an example of theinvention is illustrated and wherein: p

Figural is an isometric view of a corner of a wall constructed inaccordance with this invaention, parts being illustrated in section, an

Fig. 2 is an enlarged isometric detail of the tiles.

In the drawings the numeral 1 designates a hollow plastic tile which isformed primarily of vertical side members 2 connected by a web portion 3and surmounted by a rib or tenon 4, a longitudinal mortise 5 beingdisposed under the web portion. The tile presents an angularcross-section which with the rib omitted is rectangular. Verticallongitudinal air spaces or passages 6 are provided, one in each sidemember; while aninverted T-shaped longitudinal air passage 7 is providedover the web 3 and at the intersection of the rib. The rib also has alongitudinal air space 8 in its upper portion as shown. It will be notedthat the walls and partitions of the tile are comparatively thin, yetdisposed in such a way as to give the required rigidity and strength.

In each tile near its ends vertical air wells or ducts 9 are formed.These ducts are located so that when the tiles are set up in break-jointorder, said ducts will register and form vertical air shafts or flues asshown in Fig. 1 in section.

In building a wall acourse of tiles is laid and the next course laidthereon in breakjoint order. In handling the tiles the rib provides anexcellent means for grasping and holding the tile while placing thesame. The tile of the second course is set on the first tile so thatmortise 5 receivesthe tenon 4 as shown. Before placing the tile mortaris laid on top of the side members 2 and is separated by the tenon 4-.When the tile is placed on the mortar it will be seen that moisture ,topass from one strip of mortar would have to first pass upward and overthe tenon, which is hardly possible.

One of the pleasing features of this invention is that the exposedportions of the tiles are regular in size and shape and therefore ifdesired no finishing facing need be added to obtain a neat looking wall.In building a wall it will be necessary to have tiles of particularconstruction for forming the corners and in Fig. 1 I have shown at 10and 12 two such tiles. These tiles each have an air duct 14 in one endand these ducts register to provide a vertical air flue at the corner ofthe wall. p

A wall constructed of these tiles will not only be strong and withstandall stresses and strains, both superimposed and shearing, but will bemoisture-proof and insulated against the transmission of sound and heatand cold. The wall may be quickly and easily built and will beof apermanent nature.

What I claim is:

An interlocking tile having a longitudinal tenon on its upper side and alongitudinal mortise in itsunder side, the tenon having a longitudinalpassage wholly included therein, the portion of the tile intermediatethe tenon and mortise havingalongitndinal above and below it, and theportions of the passage extending entirely therethrough, the tile onopposite sides of the mortise each tile having vertical ducts connectedwith the having a longitudinal passage extending en- 13 said passagesand set in from the ends of the tirely therethrough. I

5 tile and extending entirely through the tile In testimony whereof Iafix my signature.
